Heavy-duty seamless black steel tube 168x20 is a reinforced industrial hollow section designed for critical engineering applications requiring extreme material density and pressure resistance. Manufactured from high-quality structural steel P235TR1 (Steel 20 equivalent) through the hot rolling of solid cylindrical billets, this pipe provides a completely monolithic structure without any longitudinal weld seams. With an outer diameter of 168 mm and a reinforced 20.0 mm wall, it offers an exceptional safety factor against internal rupture.

The product is dual-certified under EN 10216-1 for pressure pipelines and EN 10210-2 for hot-finished structural sections (3.1 + CE certified), meeting rigorous European safety standards. The extra wall thickness makes it an ideal choice for high-pressure steam distribution systems, industrial boiler networks, and primary structural nodes in bridge pylons or architectural columns. The seamless construction ensures uniform mechanical properties along the entire length, eliminating risks associated with weld fatigue or failure during thermal expansion. Steel 20 grade provides excellent weldability and ductility.

The untreated black surface allows for easy application of project-specific anti-corrosive insulation or painting. Available for self-pickup from logistics hubs in Poland, Bulgaria, and Ukraine. We offer professional high-precision band-saw cutting services to meet your exact length requirements. Wholesale prices apply for bulk orders starting from 1 ton.
